Do I really need to keep electronic records in their original file format, or can I convert everything to PDF?

The short answer is: it depends, and “convert everything to PDF” is rarely the right blanket rule. PDF (especially the archival PDF/A profile) is an excellent preservation format for documents that are essentially fixed pages of text and images. But many electronic records are not page-based, and forcing them into PDF can strip away exactly the qualities that make them reliable records.

What you can lose in conversion

A record is more than its visible content. To be trustworthy, it must keep its content, context, and structure over time. Converting to PDF can discard:

• Functionality — formulas in a spreadsheet, links in a database, or fields in a form become a flat, non-working snapshot.
• Metadata — authorship, timestamps, version history, and audit trails that establish authenticity and chain of custody.
• Searchability and reuse — structured data (CSV, XML, geospatial, email headers) may no longer be machine-readable for analysis or discovery.

For litigation and FOIA, courts and requesters often expect records in a form that preserves this underlying information, not just a printed-looking image.

A better way to think about it

Match the preservation approach to the record type and to your retention obligations:

• Documents (memos, reports, signed letters) — PDF/A is usually a sound, stable choice.
• Data and dynamic records (spreadsheets, databases, forms, email) — keep the native or an open, well-documented format; export a PDF copy only as a supplement if a fixed view is needed.
• Long-retention and permanent records — favor open, non-proprietary formats and plan for periodic format migration as software ages.

The goal is to keep each record usable, authentic, and complete for its full retention period, whatever format best achieves that.

Practical guidance

Document your format decisions in policy rather than deciding file by file. Before converting, confirm the target format preserves the information you are legally and operationally required to keep, and retain the original until you have verified the converted copy is a faithful, complete substitute.

Converting to PDF is a tool, not a universal answer. Use it where it fits, and preserve native formats where the record’s value lives in its structure and data.
